Power factor improvement of a thyristor controlled, inductive load with fixed capacitor, thyristor-controlled reactor (fc-tcr) type compensator. Research report
A detailed analysis was carried out of a fixed capacitor thyristor-controlled reactor type compensator, for dynamic power factor correction and terminal voltage stabilization of a thyristor phase-controlled inductive load. An equation for the firing angle of the reactor and Fourier coefficient equations of the load current, supply current and compensator current were derived and compared for typical circuits. Variation with load thyristor firing angle of the rms values of these currents, the firing angle of the compensator thyristor, the power factor and other quantities were tabulated and plotted as graphs. The magnitudes of different harmonic components of the three currents were also determined. It was discovered that, for load phase angles of less than 45 degrees, the load susceptance must be such that the lagging reactive component of the fundamental component of the load current at most load thyristor firing angles.
